My 2000 Jetta 1.8T has been perfect. At 75,000 miles, I got the engine light on and my VAG COM software has scanned one fault code:
17536 Fuel Trim: Bank 1 (mult): System too lean
this seems to be an intermittant problem as the light has gone out on its own and then came back. When the light is on, my car is definately not as powerful as it usually is when normal.
What part under the hood is this? Dont have the Bently or factory manual to figure out. I know it is fuel mixture and think that it may be the MAF sensor. Has anyone else had this problem? How did you fix it?
If it is the MAF, are there any aftermarket high performance ones out there?
Thanks - Andy.
